Description

Technical Field

[0001] The utility model relates to the technical field of crucible furnaces, in particular to a crucible furnace for smelting aluminum alloys with a protective structure. Background Art

[0002] Crucible furnace is the simplest smelting equipment, mainly used to melt non-ferrous metals with low melting points, such as copper, aluminum and their alloys. The production of aluminum alloy wheels requires the use of a crucible furnace to melt the material and then die-cast it.

[0003] According to a disclosed electrically heated crucible furnace (publication number: CN215766440U), in the above application, rollers are provided to facilitate the movement of the overall structure, and other auxiliary structures are convenient for displacement or replacement and maintenance of the crucible furnace, which is simple and efficient, and the support frame can enhance the supporting capacity of the main body so that other structures can tilt the main body, and the rotating shaft drives the main body to tilt through a rotating motor, which is convenient for other structures to collect materials inside the main body, and the fixed setting of the bogie and the fixed frame can assist in enhancing the tilting operation of the overall structure on the main body, and the structure is stable.

[0004] Although the above technical solution can move the entire device using rollers, the stability of the main body is poor. When the main body is tilted, the molten aluminum inside it is prone to shaking, which may cause the center of gravity of the main body to change, causing the main body to shift using the rollers, which may easily cause the aluminum to spill out during the process of pouring it into the container. Once the high-temperature aluminum spills, it will affect the surrounding environment and may even scald the staff, posing a safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6As shown, the utility model provides a technical solution: a crucible furnace for aluminum alloy smelting with a protective structure, comprising a furnace body 1, a furnace cover 2 is installed on the top of the furnace body 1 by bolts, the bolts connecting the furnace cover 2 and the furnace body 1 are disassembled to separate the furnace cover 2 from the furnace body 1, so that the furnace body 1 can be opened, a rotating shaft 3 is fixedly installed on the outer wall of the furnace body 1, a support plate 4 is rotatably connected to the outer wall of the rotating shaft 3, a base 5 is fixedly installed on the bottom of the support plate 4, and a side wall of the base 5 is rotatably connected to a roller 6, the base 5 can be moved by the roller 6, so that the furnace body 1 can be transferred, a motor 7 is fixedly installed on the outer wall of the support plate 4, and the rotating shaft 3 on the left side of the furnace body 1 passes through the support plate 4 and is fixed Installed at the output end of the motor 7, the rotating shaft 3 is rotatably connected with the penetration point of the support plate 4. The motor 7 is started to drive the rotating shaft 3 to rotate, so that the rotating shaft 3 drives the furnace body 1 to rotate, so that the molten aluminum water inside the furnace body 1 can be poured out. A supporting mechanism 8 for improving the stability of the furnace body 1 is provided on the base 5. By setting the supporting mechanism 8, the base 5 can be lifted up and the roller 6 can be suspended in the air, so that the base 5 can be prevented from sliding during the rotation of the furnace body 1, so that the furnace body 1 is in a stable state during the pouring of the aluminum water. A limiting mechanism 9 is provided on the rotating shaft 3. The rotating shaft 3 can be limited by setting the limiting mechanism 9, so that the furnace body 1 can maintain a stable vertical state during the movement of the base 5.

[0026] The above-mentioned supporting mechanism 8 includes a supporting seat 81, a two-way screw rod 82, a slider 83, a side plate 84, an inclined groove 85, a hand wheel 86, a guide rod 87, and a rubber pad 88; the supporting seat 81 is slidably connected to the inner wall of the base 5, a rubber pad 88 is fixedly installed at the bottom of the supporting seat 81, and a side plate 84 is fixedly installed on the top of the supporting seat 81. The end of the side plate 84 away from the supporting seat 81 passes through the base 5, and the side plate 84 is slidably connected to the penetration of the base 5. The side plate 84 is provided with an inclined groove 85, and the supporting seat 81 is driven to slide downward on the inner wall of the base 5 through the side plate 84 until the rubber pad 88 at the bottom of the supporting seat 81 is attached to the ground and the base 5 is lifted up, so that the roller 6 is suspended in the air. At this time, the supporting seat 81 can be used to stably support the base 5 to prevent the base 5 from slipping during the rotation of the furnace body 1. The movement of the two-way screw rod 82 makes the furnace body 1 in a stable state during the pouring of molten aluminum. One end of the two-way screw rod 82 is rotatably connected to the side wall of the support plate 4, and the other end of the two-way screw rod 82 passes through the support plate 4 and is fixedly installed with a hand wheel 86. The two-way screw rod 82 is rotatably connected to the penetration of the support plate 4, and the slider 83 is threadedly connected to the outer wall of the two-way screw rod 82. The bottom of the slider 83 is attached to the upper surface of the base 5. The rotation of the two-way screw rod 82 can drive the two groups of sliders 83 threadedly connected thereto to slide synchronously in opposite directions and approach each other. A guide rod 87 is fixedly installed on the side wall of the slider 83, and the outer wall of the guide rod 87 is attached to the inner wall of the inclined groove 85. When the two groups of sliders 83 approach each other, the guide rod 87 will squeeze the inclined groove 85, so that the side plate 84 drives the support seat 81 to slide downward on the inner wall of the base 5.

[0027] The above-mentioned limiting mechanism 9 includes a cam 91 and a limiting plate 92; the cam 91 is fixedly mounted on the outer wall of the rotating shaft 3, and the side wall of the side plate 84 is fixedly mounted with the limiting plate 92, and the limiting plate 92 is attached to the outer wall of the cam 91. When the side plate 84 drives the support seat 81 to slide upward and reset on the inner wall of the base 5, the side plate 84 will drive the limiting plate 92 to move upward synchronously, so that the limiting plate 92 can be attached to the side wall of the cam 91 again. The limiting plate 92 cooperates with the cam 91 to limit the rotating shaft 3, so that the rotating shaft 3 cannot drive the furnace body 1 to rotate. When the base 5 moves using the roller 6, the rotating shaft 3 can be limited to keep the furnace body 1 in a stable vertical state at all times.

[0028] Working principle: When the aluminum liquid in the furnace body 1 needs to be poured out, the hand wheel 86 is used to rotate the bidirectional screw rod 82. The rotation of the bidirectional screw rod 82 can drive the two sets of sliders 83 connected with the screw rod 82 to slide synchronously in opposite directions and approach each other. At the same time, the slider 83 drives the guide rod 87 to fit the inner wall of the inclined groove 85 and move synchronously. At this time, the guide rod 87 squeezes the inclined groove 85, so that the side plate 84 drives the support seat 81 to slide downward on the inner wall of the base 5 until the rubber pad 88 at the bottom of the support seat 81 fits the ground and lifts up the base 5, so that the roller 6 is suspended in the air. The support seat 81 can provide stable support for the base 5, and then the bolts connecting the furnace cover 2 and the furnace body 1 are removed to separate the furnace cover 2 from the furnace body 1, and then the motor 7 is started to drive the rotating shaft 3 to rotate, so that the rotating shaft 3 drives the furnace body 1 to rotate, so that the molten aluminum water inside the furnace body 1 can be poured out, and the support of the support seat 81 makes the roller 6 suspended in the air, which can prevent the base 5 from sliding during the rotation of the furnace body 1, and make the furnace body 1 in a stable state during the pouring of the aluminum water, thereby preventing the furnace body 1 from shifting during the pouring of the aluminum water, causing the aluminum water to spill and causing a safety accident.

[0029] When the side plate 84 drives the support seat 81 to slide downward on the inner wall of the base 5, it will drive the limit plate 92 to move downward synchronously, so that the limit plate 92 can be separated from the side wall of the cam 91, so that the shaft 3 can be rotated, so as to facilitate the pouring of the molten aluminum inside the furnace body 1. After the molten aluminum inside the furnace body 1 is poured out, the motor 7 drives the shaft 3 to rotate, so that the shaft 3 drives the furnace body 1 to rotate to a vertical state. At this time, the hand wheel 86 is used to rotate the bidirectional screw rod 82, so that the bidirectional screw rod 82 drives the two sets of sliders 83 to move away from each other. At this time, the guide rod 87 and the inclined groove 85 can cooperate to make the side plate 84 drives the support seat 81 to slide upward on the inner wall of the base 5 to reset. At this time, the side plate 84 will drive the limit plate 92 to move upward synchronously, so that the limit plate 92 can be fitted to the side wall of the cam 91 again. At this time, the limit plate 92 can cooperate with the cam 91 to limit the rotating shaft 3, so that the rotating shaft 3 cannot drive the furnace body 1 to rotate. When the base 5 is moved by the roller 6, the furnace body 1 can always maintain a stable vertical state by limiting the rotating shaft 3, so that the high-temperature molten aluminum can be in a relatively stable state inside the furnace body 1, avoiding the shaking of the molten aluminum and causing safety accidents.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
